Among the following ethers, which one will produce methyl alcohol on treatment with hot concentrated HI?

1. CH₃—CH₂—CH—O—CH₃
2. CH₃—C—O—CH₃
3. CH₃—CH₂—CH₂—O—CH₃
4. CH₃—CH₂—CH₂—O—CH₃

Correct answer: CH₃—CH₂—CH₂—O—CH₃

Solution

When ethers react with hot concentrated HI, cleavage occurs at the C-O bond. In CH₃—CH₂—CH₂—O—CH₃, the bond breaks to form CH₃OH (methyl alcohol) and CH₃CH₂CH₂I.
